' In Great Britain November 16, 1932 5 Claims.

The object of this invention is to provide means in connection with awater closet whereby the noise created during the flushing of the pancan be silenced. 7

For the purpose of my invention I'provide a sliding panel, door or thelike in connection with the pan or appliances fitted thereto, such panelbeing connect-ed by suitable mechanism with the fold down cover, so thaton lifting the cover, the

sliding panel is moved free of the opening of the pan and on a closingof the cover, the sliding panel will be moved to cover the opening ofthe pan and close same, whereby the noise of the flushing will begreatly reduced, and this silencing can be further attained by providingthe 'cover with a rubber or other cushion which rests on the seat.

My invention will be clearly understood from the following descriptionaided by the annexed drawings which illustrate two examples of carryingmy invention into effect, and in which the panel is moved by mechanismconnected with the cover of a seat of a water closet, but it must beunderstood that other means or mechanism for actuating the panel may beemployed.

Figure 1 is a side sectional elevation of a closet pan with the coveropen and actuating mechanism in position with the sliding panel in thenon-operative position.

Figure 2 is a similar view to Figure 1, but showing the mechanism inposition, and sliding panel sealing the pan with the cover closed.

Figure 3 is a plan of Figure 1.

Figure 4 is a plan view of the actuating mechanism showing its positionwhen the sliding panel is in the non-operative position. 7

Figure 5 is a side sectional elevation of a modified construction.

According to Figures 1 to 3, the pan [0, is constructed at its upper orflushing rim portion H with the back portion l2 having its rear edgestraight, and through this back portion I2 is formed a slot or openingl3 coinciding with a groove in the inside wall of the rim portion H, theopposite sides of which groove run parallel to about the centre of theopening of the pan l0, and then continue in a curve around the insidefront edge of the rim Ii.

Instead of the front portion being curved, it may be any other shape,and the front of the panel shaped accordingly.

This groove is preferably lined with a strip l4 cemented therein.

At the back of the pan l0 underneath the slot l3 are positioned bracketsl5, 15 carrying guide rails l6, it, these being positioned in line withthe bottom of the groove and slot.

' H is the usual seat hinged at i8 as usual to the frame l9 whichextends behind the pan l0.

At a line above the hinge l8'the cover 20 is 5 hinged at 2|'to the seatframe [9.

The panel 22 comprises a sheet of glass or other material of a width tofit the strip M of the groove and shaped at one edge to fit'the frontportion of the strip I4, and its back edge carries a bracket 23 to whichis connected collapsible and extensible mechanism known as lazy-tongs,and comprising two rods 24, 24, extending from the bracket and eachpivotallycarrying at its end another rod 25, 25,'these beingpositionedin a. reverse direction to the rods 24, 24, and connected attheir ends to ends of rods 26, 26 pivoted together at their centres, theother ends of these rods being pivotally connected to other rods 2?, 2ipivoted together at their other ends to a bracket 28 fixed to the framel9.

To the pivots of the ends of the rods 26, 21 are pivotally. connectedother rods 29, 29, and these are pivotally connected together at theirfree ends and to a bracket 36 connected by a link 3| with a bracket 32on the top side of the cover 20.

The bracket 30 is slidable in a slot 33 cut in the frame I9. 7 i

In action and assuming the cover, mechanism and panel are in theposition shown at Figure 1, the pan being open, on the lowering of thecover 20 the link 3| will pull on the rods 29 and tend to straightenthem, and these in turn will open out the rods 21 and at the same timeopen out the cross rods 26, and these in turn will open out the rods 25which will draw together the rods 24, and in so doing the distancebetween the outer ends of the rods 24 and the bracket 28 will beshortened, and the panel 22 will be moved along the groove to seal thepan as shown at Figure 2, and a lifting of the cover will effect areverse movementof the rods and draw the panel back clear of the openingin the pan as at Figure 1.

According to Figure 5, instead of forming the groove and U strip in theflushing rim of the 45 pan I0, I may form such rim and slotted rearportion as a separate article I l and aflix same to the top of theflushing rim 1 l of a closet pan and in other respects the constructionis the same.

The cover may also be provided with overbalance weights or other devicesto normally close the seat when the seat is unoccupied.

As a further security in preventing the noise of flushing issuing fromthe pan the under part of the seat as also the underpart of the cover 55may be provided with a soft rubber ring to contact with the flushing rimor separate rim and the seat, and thus further assist in silencing thesound.

I may connect the cover or the seat or the operating mechanism by chainor otherwise, with the valve lever of the flush cistern, so that thevalve may be actuated to flush the pan on the movement of the cover,seat or mechanism on closing the panel.

What I do claim as my invention and desire to obtain by Letters Patentis:-

1. In a water c1oset having a flushing pan provided with an opening atthe top thereof and a movable cover for said pan opening, a closuremember slidable rectilinearly transversely of said pan opening to openand close it, an element slidable in the rear of the cover, a connectionfrom said element to the top of said cover, and extensible andcontractible means connecting the element, said closure member and afixed part operative to slide said closure member into position to closethe pan opening to render the flushing operation noiseless throughclosing of the cover and to slide said closure member into open positionthrough opening of the cover.

' 2. In a water closet having a frame, a flushing 'pan provided with anopening in the top thereof and a cover for opening and closing said panopening, a closure member and a cooperative guiding groove provided withparallel sides in which said closure member is slidable directly intopositions to close and open said pan opening, an element slidablymounted in said frame, a connection from said element to the top of saidcover, and extensible andcontractible means connecting said element,closure member and frame operative to slide said closure member in saidgroove into position to close said pan openi'ng through closing of thecover and thereby seal the pan opening, and to slide said closure memberinto open position with respect to said pan opening through opening ofthe cover and thereby uncover the pan opening.

'3. In a mechanism for sliding a closure of a pan to and from open andclosed positions through movement of a cover to open and closedpositions, a lazy-tong mechanism, anchoring means for a part of saidmechanism, rods extending forwardly from the rear of said mechanismconnected to said closure, a slidable element connected to saidmechanism, and a connection from said slidable element to the outer sideof said cover.

4. In a mechanism for sliding a closure of a pan to and from open andclosed positions through movements of a cover to and from open andclosed positions, a frame having a slot, a lazy-tong mechanism, abracket slidable in said slot and connected to said mechanism, aconnectionirom said bracket to the outer side of said cover, meansanchoring a part of said mechanism, and means connecting a part of saidmechanismto said closure.

, 5. In a mechanism for sliding a closure of a pan to and from open andclosed positions through movements of a cover to and from open andclosed positions, a frame having a slot, a lazytong mechanism, a bracketslidable in said slot, rods pivoted to said bracket and connected toseparate pivots of said mechanism, a connection from said bracket to theouter side of said cover, means anchoring said mechanism at one end, androds pivoted to the mechanism adjacent the other end, the latter rodsextending forwardly and being connected to the closure.
